Description

Technical Field

[0001] This utility model relates to the field of tape wrapping machines, specifically to a tape wrapping machine horn breakage detection device. Background Technology

[0002] The main function of a wrapping machine is to wrap the insulated core wires of electrical wires, power cables, control cables, optical cables, etc. It wraps the wrapping tape (such as mica tape, cotton paper tape, aluminum foil, polyester film, etc.) around a horn-shaped piece. The horn-shaped piece rotates on the outside of the core wire, thus wrapping the tape around the core wire to achieve insulation and protection.

[0003] During the operation of the wrapping machine, the wrapping tape is wrapped around the horn-shaped piece. The horn-shaped piece supports and guides the wrapping tape. During the wrapping process, the wrapping tape will be subjected to a certain amount of tension. Therefore, if the tension is too great, the wrapping tape will break. If the tape feeding action is not stopped in time, the wrapping tape will continue to be output and accumulate on the horn-shaped piece. The accumulated wrapping tape is easy to get tangled on the rotating parts of the equipment, making subsequent manual cleaning difficult and affecting production efficiency. Utility Model Content

[0004] The purpose of this utility model is to provide a tape breakage detection device for a tape wrapping machine. This device determines whether the tape is broken by winding the tape around the detection roller and detecting the rotation speed of the detection roller through a speed measuring device. It also reduces the risk of tape accumulating on the tape horn or even getting tangled on the rotating parts of the equipment by controlling the active tape feeding mechanism to stop working.

[0005] The technical solution adopted by this utility model to solve the above problems is:

[0006] A tape breakage detection device for a tape wrapping machine includes a horn-shaped component and a detection roller. The detection roller is rotatably mounted on the horn-shaped component, and a guide wheel assembly is provided on the horn-shaped component. The tape is wound around the detection roller and the guide wheel assembly. A speed measuring mechanism for measuring the rotational speed of the detection roller is provided on the horn-shaped component. A connector is fixedly connected to the right end of the horn-shaped component, and an active tape feeding mechanism for conveying the tape is provided inside the connector. When the speed measuring mechanism detects a decrease in the rotational speed of the detection roller, it controls the active tape feeding mechanism to stop working.

[0007] In the above technical solution, preferably, the speed measuring mechanism includes a Hall switch and several magnetic components. The magnetic components are fixed at equal intervals around the front end of the detection roller. The Hall switch is fixed on the horn-shaped component and is close to the magnetic components. The Hall switch is connected to a wireless transmission terminal with a built-in power supply.

[0008] In the above technical solution, preferably, the active feeding mechanism includes an active wheel and a driven wheel, the tape is clamped between the active wheel and the driven wheel, the right end of the connector is fixed with a main shaft, the main shaft is rotatably arranged in the tape wrapping machine and driven to rotate by the drive device in the tape wrapping machine, and a transmission mechanism is provided between the main shaft and the active wheel.

[0009] In the above technical solution, preferably, the transmission mechanism includes a first gear, a second gear, a third gear, and a fourth gear. The first gear and the second gear are two bevel gears that mesh with each other. The third gear and the second gear are coaxially fixed and rotatably disposed in the connecting member. The fourth gear is coaxially fixed with the driving wheel and meshes with the third gear.

[0010] In the above technical solution, preferably, both the front and rear ends of the driven wheel are provided with sliders, and the front and rear ends of the driven wheel are respectively rotatably disposed in the two sliders.

[0011] In the above technical solution, preferably, a first guide wheel is rotatably provided inside the connector, and a second guide wheel and a third guide wheel are rotatably provided on the horn piece, with the second guide wheel close to the right end of the horn piece and the third guide wheel located at the left end of the horn piece.

[0012] In the above technical solution, preferably, the surfaces of the driving wheel, driven wheel, first guide wheel, second guide wheel, third guide wheel and detection roller are all provided with a rubber coating layer, and the rubber coating layer on the surface of the detection roller is provided with anti-slip texture.

[0013] Compared with the prior art, this utility model has the following advantages and effects:

[0014] This invention involves winding the strapping tape around a detection roller and a guide wheel assembly. When the strapping machine is wrapping, the active feeding mechanism continuously and stably outputs the tape to the corner piece. Simultaneously, the movement of the tape drives the rotation of the detection roller. Therefore, when the wrapping speed remains stable, the rotation speed of the detection roller also remains relatively stable. Thus, when the speed measuring mechanism detects a significant decrease in the rotation speed of the detection roller, it can be determined that the tape has broken or run out. At this point, by controlling the active feeding mechanism to stop working, the risk of the tape being continuously output by the active feeding mechanism and accumulating on the corner piece or even entangled in the rotating parts of the equipment in the event of tape breakage can be reduced. This reduces the difficulty of subsequent manual cleaning and the impact on production efficiency. Attached Figure Description

[0022] The present invention will be further described in detail below with reference to the accompanying drawings and through embodiments. The following embodiments are explanations of the present invention, but the present invention is not limited to the following embodiments.

[0023] See Figures 1-6 This embodiment discloses a tape breakage detection device for a tape wrapping machine, comprising a horn-shaped component 1 and a detection roller 2. The detection roller 2 is rotatably mounted on the horn-shaped component 1. A guide wheel assembly is provided on the horn-shaped component 1. The tape 8 is wound around the detection roller 2 and the guide wheel assembly. A speed measuring mechanism 3 for measuring the rotational speed of the detection roller 2 is provided on the horn-shaped component 1. A connecting component 4 is fixedly connected to the right end of the horn-shaped component 1. An active tape feeding mechanism 5 for conveying the tape 8 is provided inside the connecting component 4. When the speed measuring mechanism 3 detects that the rotational speed of the detection roller 2 decreases, it controls the active tape feeding mechanism 5 to stop working.

[0024] This invention involves winding the strapping tape 8 around the detection roller 2 and the guide wheel assembly. When the strapping machine is wrapping, the active feeding mechanism 5 continuously and stably outputs the strapping tape 8 onto the horn-shaped piece 1. Simultaneously, the movement of the strapping tape 8 drives the rotation of the detection roller 2. Therefore, when the wrapping speed remains stable, the rotation speed of the detection roller 2 also remains relatively stable. Thus, when the speed measuring mechanism 3 detects a significant decrease in the rotation speed of the detection roller 2, it can be determined that the strapping tape 8 has broken or been exhausted. At this time, by controlling the active feeding mechanism 5 to stop working, the risk of the strapping tape 8 being continuously output by the active feeding mechanism 5 and accumulating on the horn-shaped piece 1 or even getting tangled on the rotating parts of the equipment in the event of a strapping tape breakage can be reduced, thus reducing the difficulty of subsequent manual cleaning and the impact on production efficiency.

[0025] See Figure 1 , Figure 2 The speed measuring mechanism 3 includes a Hall switch 31 and several magnetic components 32. The magnetic components 32 are fixed at equal intervals around the front end of the detection roller 2. The Hall switch 31 is fixed on the horn-shaped component 1 and is close to the magnetic components 32. The Hall switch 31 is connected to a wireless transmission terminal 33 with a built-in power supply.

[0026] In this invention, the wireless transmission terminal 33 establishes communication with the control center of the tape-making machine via a wireless local area network such as 4G, LoRa, or WiFi. The control center uses a PLC to process and transmit data. When the detection roller 2 is driven to rotate by the tape 8, several magnetic components 32 at the front end of the detection roller 2 sequentially approach and then move away from the Hall switch 31, thereby generating a continuous electrical signal in the Hall switch 31 through the Hall effect. The electrical signal is transmitted to the control center of the tape-making machine via the wireless transmission terminal 33, and the rotational speed of the detection roller 2 is derived by detecting the frequency of the electrical signal. The rotational speed of the detection roller 2 can be easily detected by the Hall switch 31 and the wireless transmission terminal 33, while avoiding the wiring difficulties caused by the Hall switch 31 needing to follow the rotation of the horn-shaped component 1 when using wired transmission. Both the Hall switch 31 and the wireless transmission terminal 33 are powered by a built-in power supply.

[0027] See Figure 3 , Figure 4 The active feeding mechanism 5 includes an active wheel 51 and a driven wheel 52. The wrapping tape 8 is clamped between the active wheel 51 and the driven wheel 52. The right end of the connecting piece 4 is fixed with a main shaft 6. The main shaft 6 is rotatably installed in the wrapping machine and driven to rotate by the drive device in the wrapping machine. A transmission mechanism 7 is provided between the main shaft 6 and the active wheel 51.

[0028] The horn-shaped component 1, the connecting component 4, and the main shaft 6 are fixed as a whole. When the main shaft 6 is driven to rotate by the drive device (e.g., a motor) inside the tape wrapping machine, the horn-shaped component 1 and the connecting component 4 can rotate simultaneously, thereby achieving the purpose of winding the tape 8 on the horn-shaped component 1 onto the core wire. At the same time, when the main shaft 6 rotates, it can drive the drive wheel 51 to rotate through the transmission mechanism 7. Since the tape 8 is clamped between the drive wheel 51 and the driven wheel 52, it can drive the tape 8 to be output onto the horn-shaped component 1, achieving the purpose of active tape feeding. This can improve the stability of tape feeding during the operation of the tape wrapping machine, reduce the risk of tape 8 getting stuck, and reduce the failure rate of the equipment.

[0029] See Figure 3 The transmission mechanism 7 includes a first gear 71, a second gear 72, a third gear 73, and a fourth gear 74. The first gear 71 and the second gear 72 are two bevel gears that mesh with each other. The third gear 73 and the second gear 72 are coaxially fixed and rotatably disposed in the connecting member 4. The fourth gear 74 is coaxially fixed with the driving wheel 51 and meshes with the third gear 73.

[0030] Through the transmission action between the first gear 71, the second gear 72, the third gear 73 and the fourth gear 74, the drive wheel 51 can rotate simultaneously when the main shaft 6 rotates. This avoids the need to set up a separate drive device (such as a motor) in the connecting part 4 to drive the drive wheel 51 to rotate, thereby avoiding the situation where it is difficult to connect the drive device to the wire when the connecting part 4 rotates, which would cause the drive device to have difficulty supplying power. At the same time, it reduces the working energy consumption of the tape wrapping machine.

[0031] See Figures 4-6 The driven wheel 52 is provided with sliders 53 at both ends, and the driven wheel 52 is rotatably disposed in the two sliders 53 respectively. The sliders 53 are slidably disposed in the connecting member 4, and a lead screw motor 54 is provided above the sliders 53 to drive the sliders 53 to move up and down.

[0032] In this invention, the lead screw motor 54 can be used with a wireless motor controller. The control center of the tape machine transmits signals to the wireless motor controller to control the lead screw motor 54, thereby solving the problem of difficulty in wiring the lead screw motor 54 when the connector 4 is rotating. The lead screw motor 54 can be powered by wiring with the power supply built into the wireless transmission terminal 33.

[0033] When the control center of the tape wrapping machine receives and deduces that the rotation speed of the detection roller 2 has decreased significantly, the control center will transmit the control signal to the wireless controller of the motor, thereby controlling the screw motor 54 to drive the slider 53 to move upward, so that the driven wheel 52 moves upward and separates from the driving wheel 51. The clamping effect of the driving wheel 51 and the driven wheel 52 on the tape 8 disappears. At this time, even if the driving wheel 51 is still rotating, it cannot achieve the effect of actively feeding the tape, thereby ensuring that the tape feeding can be stopped in time in the event of tape 8 breakage, reducing the risk of tape 8 accumulating on the horn piece 1 or even getting tangled on the rotating parts of the equipment.

[0034] See Figure 4 , Figure 5 The connector 4 is rotatably provided with a first guide wheel 41, and the horn piece 1 is rotatably provided with a second guide wheel 11 and a third guide wheel 12. The second guide wheel 11 is close to the right end of the horn piece 1, and the third guide wheel 12 is located at the left end of the horn piece 1.

[0035] After the strapping tape 8 enters the connector 4, it is first guided by the first guide wheel 41, which makes it easier to insert the strapping tape 8 between the driving wheel 51 and the driven wheel 52. After the strapping tape 8 passes through the driving wheel 51 and the driven wheel 52, it wraps around the detection roller 2. This increases the contact area between the strapping tape 8 and the detection roller 2, thereby increasing the friction between the strapping tape 8 and the detection roller 2 and reducing the probability of slippage between the strapping tape 8 and the detection roller 2. Then, the strap 8 is placed on the underside of the second guide wheel 11 and finally on the upper side of the third guide wheel 12. Compared with the existing method in which the strap 8 is placed on the outside of the two guide wheels in the horn-shaped piece 1, this embodiment allows the strap 8 to be located inside the horn-shaped piece 1 and staggered on the second guide wheel 11 and the third guide wheel 12. This can reduce the air resistance experienced by the strap 8 when the horn-shaped piece 1 rotates at high speed, reduce the probability of the strap 8 separating from the second guide wheel 11 and the third guide wheel 12 due to air resistance and centrifugal force, and tighten the strap 8, thereby ensuring the stability and uniformity of the strap 8 winding on the core wire.

[0036] The surfaces of the driving wheel 51, driven wheel 52, first guide wheel 41, second guide wheel 11, third guide wheel 12 and detection roller 2 are all provided with a rubber coating layer, and the rubber coating layer on the surface of the detection roller 2 is provided with anti-slip texture.

[0037] The rubber coating increases the friction between the tape 8 and the drive wheel 51, driven wheel 52, first guide wheel 41, second guide wheel 11, third guide wheel 12, and detection roller 2, reducing the probability of tape 8 wear due to sliding friction. Simultaneously, the rubber coating provides shock absorption, reducing the risk of tape 8 breakage due to excessive instantaneous stress during tape machine operation. The rubber coating can be made of rubber. The anti-slip texture further reduces the probability of slippage between the tape 8 and the detection roller 2, ensuring that the rotational speed of the detection roller 2 matches the conveying speed of the tape 8.

[0038] The above description in this specification is merely illustrative of the present invention. Those skilled in the art to which this invention pertains may make various modifications or additions to the described specific embodiments or use similar methods to replace them, as long as they do not depart from the content of this specification or exceed the scope defined in the claims, all of which shall fall within the protection scope of this invention.
